Artificial Insemination

The artificial insemination (AI) is a frontline assisted reproduction technique and that is based on the natural fertility. In this procedure, a semen sample (previously prepared from the laboratory) is inserted directly into the uterus.
It can be performed during a spontaneous cycle or a soft ovarian stimulation.
Artificial insemination can be from a married couple, or sperm from a donor (the use of the semen from the partner or spouse).
Artificial insemination is usually recommended for a maximum of 3-4 cycles of treatment (although it always depends on each case) after which, if the pregnancy is not successful; the next step would be therapeutic stage with vitro fertilization (IVF).

Intrauterine artificial insemination step by step

The cycle starts with menstruation. Normally, in a spontaneous or natural cycle one dominant follicle (structure that houses the egg) develops. However, to optimize the technique is generally recommended hormone therapy to stimulate the ovaries to obtain a greater number of follicles, but always in a limited number in order to increase the chance of getting pregnant without risking multiple pregnancies.

The beginning of the stimulation is performed within the first five days of the menstrual cycle by daily subcutaneous injections of hormones. The cycle of stimulation vary with each patient but on average around eight to ten days.

During the stimulation treatment a number of gynaecological ultrasound and / or hormonal analyses are performed. 2-3 half-cycle controls are performed.
This ultrasound allows us to identify the size of the follicle / follicles and determine when is the best time to trigger ovulation.

Once the follicle or follicles have reached the appropriate size, ovulation is then induced by a subcutaneous hormone injection.

Between 36-42 hours after induction of ovulation, the man must provide a semen sample. In the case of using a donor´s sperm, this will be pre-selected according to the physical characteristics of the recipient couple or woman.

The semen will be prepared in the laboratory to separate motile sperm.
Once the semen has been prepared and trained in the laboratory it is then introduced via a thin catheter into the uterus, where sperm must pass through and fertilize eggs in the fallopian tubes. A short and quick process, of which is completely painless. After the procedure, the woman rests a few minutes and then is able to continue daily life normally.

The pregnancy test is performed 12 days after insemination. Ultrasound is scheduled two weeks after a positive pregnancy test to confirm pregnancy in progress.

When is Artificial Insemination recommended?
This technique is recommended as the first procedure for a single women or homosexual couples with no previous history of infertility. Also in young heterosexual couples who have been recently trying to get pregnant, and possess any of the following requirements:

  • Idiopathic or unexplained infertility; where they have ruled out the most common infertility disorders through the basic tests.
  • Minor male factor; consists of slight alterations in seminal fluid, such as, to allow a minimum number of suitable sperm (after had been prepared in the laboratory), in order to reach the egg naturally.
  • Cervical Factor: any disease that affects the functioning of the cervix (stenosis, scarring, abnormal cervical mucus, etc.)
  • Sexual dysfunction: coital or psychological pathologies that prevent carrying out the complete stage of intercourse (erectile dysfunction, vaginismus, etc.
  • Ovulatory dysfunction: in the case of women with irregular or absent cycles (amenorrhea / oligomenorrhea), and therefore, with irregular or absent ovulation usually due to hormonal changes.
  • Severe male factor: in case of serious and irreversible male sterility (Azoospermia: no sperm in the ejaculation), and no other female sterility factor identified, may perform artificial insemination using sperm of a donor.
  • Male genetic factor when a man carries a serious genetic disease to prevent transmission to offspring may use the sperm of a donor.
